@override
Widget build(BuildContext context) {
return materialapp(
home: DatePickerDemo(),
);
}
}
class DatePickerDemo extends StatefulWidget {
@override
_DatePickerDemoState createState() => _DatePickerDemoState();
}
class _DatePickerDemoState extends State {
DateTime selectedDate = DateTime.now();
Future _selectDate(buildcontext context) async {
final DateTime? picked = await showDatePicker(
context: context,
initialDate: selectedDate,
firstDate: DateTime(2000),
lastDate: DateTime(2101),
);
if (picked != null && picked != selectedDate)
setState(() {
selectedDate = picked;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Date Picker Demo')),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(
"${selectedDate.toLocal()}".split(' ')[0],
style: TextStyle(fontSize: 30, fontWeight: FontWeight.bold),
),
SizedBox(height: 20),
